Easy Math: Astrological Chart Calculation

Olga Rozzell, PhD, Dipl IAA, CAP-ISAR


Calculating a horoscope by hand is not only a requirement for getting a certification to become a professional astrologer by many astrological organizations but also a key to deeply understanding the meaning of parts and pieces of a chart.

In this 8-classes (5 basic + 3 continuing), we will discuss the systems of space and time coordinates, calculations for the positions of planets, angles and houses cusps, and the math of lunar phases, aspects, progressions and directions, lunar returns, composite and relocated charts. The students will find out that a chart calculation involves very simple basic math but advanced logic. The 1.5-hour lessons will take place on Zoom once a week on Tuesdays starting on October 4th at 6 PM.
